Description

  The present invention relates to an input processing device that performs processing for moving display contents displayed on a display device when an indicator touching a flat input pad is moved.

  A keyboard and a mouse are used as an input processing device equipped in a personal computer, and a notebook type personal computer is equipped with a planar input member having an input pad in combination with the keyboard. . This planar input member detects a change in capacitance between electrodes when a low-potential indicator such as a human finger approaches or touches the input pad. Coordinate data can be obtained from the change in capacitance, and the control unit of the personal computer controls the same as when the mouse, which is an external device, is operated based on the coordinate data obtained from the input member. A signal is generated.

  Recently, personal computers have also appeared that input coordinate data by operating a tablet-type input device provided on a display screen with a pen or a finger.

  As described in each of the following patent documents, this type of input processing device is a display device or input pad arranged so as to overlap the input pad when moved by touching a flat input pad with a finger or the like. The content displayed on a display device provided at a different location is moved according to the direction of finger movement.

In the conventional input processing device, the display content of the display device can be moved in accordance with the moving direction of the finger by touching the input pad and moving the finger in one direction. However, when the movement of the finger is stopped or the finger is released from the input pad, the display content moving process stops and the image on the display device stops. Therefore, in order to continuously move the display contents in the same direction, it is necessary to repeatedly slide with the finger in the same area on the input pad.

  The present invention solves the above-described conventional problems, and when a process of moving a display content is performed by moving an indicator such as a finger on an input pad, An object of the present invention is to provide an input processing device that allows the display screen to continue to move while the movement locus is a curved locus so that the movement processing of the display contents can be continued with a simple operation.

The present invention changes an input member having an input pad and a detection unit that detects a position where an indicator touches the input pad, and a display content displayed on a display device based on an input signal obtained from the input member A control unit is provided,
The control unit performs the following processing.
(1) It is determined from the input signal whether or not the contact position touched by the indicator is a preset vertically long area of the input pad.
(2) Display movement processing for moving the display content in one direction when it is detected that the contact position of the indicator is moving in a straight locus in the effective direction in which the processing is effective in the vertically long region. Execute.
(3) If it is determined that the contact position moved along the linear locus has stopped while the display movement process of (2) is being performed, the display movement process is canceled.
(4) In the display movement process of (2), after the contact position of the indicator has moved a certain distance or more in the effective direction within the vertically long region, the contact position continues in one direction. when it is determined that the transition to continuous curved path, continues execution of the display moving process.

  The input processing device according to the present invention performs a display movement process when the contact position of an indicator such as a finger moves in one direction by a predetermined distance within a predetermined functional area of the input pad and then becomes a curved locus. Continue to implement. Therefore, it is not necessary to remove the indicator from the input pad many times, and the display content can be continuously moved. In addition, the movement of the display content can be stopped by stopping the movement of the indicator or moving the indicator away from the input pad. Can be done.

  The input pad of the present specification can output, as coordinate data, a position where the indicator is opposed by a change in capacitance when a low potential indicator such as a finger approaches and comes into contact. Or, the input pad is provided with a resistive film between the opposing insulators, and when the insulators are partially brought into contact with each other, the change of the resistance value is detected and the position where the indicator contacts is coordinated. It may be obtained as data.

  Further, the input pad and the display device may be located at different locations, and the display content of the display device may be changed by operating the input pad, or the input pad is transparent and provided to overlap the display device. It may be what is provided.

The present invention is, for example, the portrait area extends in the vertical direction in the input pad,
In the above (2), when the contact position of the indicator moves in the effective direction downward in the vertically long region, the display movement process moves the display content in either the upward direction or the downward direction. When the contact position of the indicator moves upward, which is the effective direction, a display movement process is performed in which the display content is moved to the other of the upward and downward directions.

In this case, in the continuation process of (4) , when the contact position of the indicator moves downward in the vertical region by a certain distance or more and then shifts to a clockwise curved locus, Continue moving the displayed content to the one side,
When the contact position of the indicator moves upward by a certain distance or more and then moves to a counterclockwise curved locus, it is possible to continue the movement of the display content to the other.

The present invention is the Vertical region extends in the lateral direction in the input pad,
In (2), the display movement process for moving the display content in either the right direction or the left direction when the contact position of the indicator moves in the right direction which is the effective direction in the horizontally long region. When the contact position of the indicator moves to the left, which is the effective direction, display movement processing is performed to move the display content to the other of the right direction and the left direction.

In this case, in the continuation process of (4) , when the contact position of the indicator moves to a right distance or more in the horizontally long region and then moves to a counterclockwise curved locus, Continue to move the display content to the one side,
When the contact position of the indicator moves to the left in a certain distance or more and then shifts to a clockwise curved locus, it is possible to continue the movement of the display content to the other.

In the continuation process (4) , when the contact position of the indicator is continuously changed from the clockwise direction to the counterclockwise direction or the counter position is changed from the counterclockwise direction to the clockwise direction, The moving direction of the display contents can be reversed.

  In the above-mentioned means, the display content can be moved in both directions by rotating the moving position of the indicator of the curved locus in the reverse direction, and access to the target position of the display content is facilitated.

  The present invention provides a display movement process for moving the display content of a display device when the contact position of a pointer such as a finger moves to a curved locus after the contact position of a pointer such as a finger has moved a predetermined distance within the function area of the input pad. continue.

  While drawing a curve with the indicator, the display contents can continue to move, and the display movement process stops when the indicator stops moving or when the indicator is released from the input pad. The input operation can be performed with a sense that the operation and the display movement process are integrated.

  FIG. 1 is a perspective view showing a notebook personal computer equipped with the input processing apparatus of the present invention, and FIG. 2 is a plan view of a planar input member. FIG. 3 is a circuit block diagram of the input processing device. 4 to 10 are flowcharts showing the processing operation of the input processing apparatus.

  In a personal computer 1 shown in FIG. 1, a main body 2 and a lid 3 are connected so as to be foldable. A keyboard device 4 and a planar input member 5 are provided on the operation panel on the surface of the main body 2. A display device 6 formed of a liquid crystal display panel is provided on the front surface of the lid 3.

  As shown in an enlarged view in FIG. 2, the planar input member 5 includes an input pad 7, a right button 8 positioned at the lower right of the input pad 7, and a left button 9 positioned at the lower left.

  The input pad 7 has a flat input surface 7a. In the input pad 7, a plurality of X electrodes extending in the X direction and a plurality of Y electrodes extending in the Y direction are opposed to each other with an insulating layer interposed therebetween, and a detection electrode is provided between adjacent X electrodes. It has been. These electrodes are covered with a thin insulating sheet, and the surface of the insulating sheet is the input surface 7a. When a finger, which is an indicator of a conductor having a substantially ground potential, touches the input surface 7a, a capacitance is formed between the finger and each electrode. The electrostatic capacitance between the X electrode changes and the electrostatic capacitance between the detection electrode and the Y electrode changes.

  As shown in FIG. 3, a pulsed voltage is sequentially applied to the X electrode from the drive circuit 11 provided in the input member 5, and a pulsed voltage is sequentially applied to the Y electrode at a different timing. The When a pulsed voltage is applied to any X electrode or Y electrode, if the indicator approaches the electrode, the voltage between the X electrode and the detection electrode is caused by the change in capacitance. Alternatively, the voltage between the Y electrode and the detection electrode changes. This change in voltage is detected by the pad detector 12 via the detection electrode. The pad detection unit 12 detects a change in voltage from the detection electrode, and obtains timing information indicating which X electrode or Y electrode the voltage is applied at that time, thereby determining the contact position of the finger on the input surface 7a. It can be detected on the XY coordinates.

  Therefore, when the finger touching the input surface 7a is moved, the movement locus of the finger can be detected on the XY coordinates. Further, when a so-called tapping operation is performed in which the finger is quickly brought close to and separated from the input surface 7a, the capacitance between the electrodes changes in a short time, and this can be detected by the pad detector 12.

  In the input member 5, an operation signal including XY coordinate information indicating the contact position of the finger on the input surface 7 a is generated by the pad detection unit 12 and is provided to the pad input signal generation unit 13. Further, an operation signal of the right button switch 8 a that is operated by pressing the right button 8 and an operation signal (click signal) of the left button switch 9 a that is operated by pressing the left button 9 are also detected by the pad detection unit 12. Then, the operation information is given to the pad input signal generation unit 13.

  In the pad input signal generation unit 13, the XY coordinate information that is the operation signal of the input pad 7 detected by the pad detection unit 12, the operation signal of the right button switch 8a, and the operation signal of the left button switch 9a are predetermined. The format data (input signal) of the number of bytes is output from the output interface 14. An input signal output from the output interface 14 is given to an input interface 21 provided in the control unit 20 of the personal computer. The output interface 14 and the input interface 21 are connected by a USB interface or the like.

  Various software is stored in the control unit 20 of the personal computer 1. The control unit 20 stores an operating system (OS) 22. The operating system 22 controls the display driver 23 and displays various information on the display device 6.

  A document tool 25 is installed in the control unit 20 as software. The document tool 25 can exhibit the function of a word processor and is accompanied by a dictionary tool 27. When the function screen of the word processor is displayed on the display device 6, characters and functions can be input by operating the keyboard, and the input character string is displayed on the screen of the display device 6.

  An input determination unit 24 is installed as software in the control unit 20, and format data (input signal) obtained from the pad input signal generation unit 13 is given to the input determination unit 24 through the input interface 21. The input determination unit 24 is accompanied by a region setting unit 26 that separates and stores the region of the input surface 7 a of the input pad 7. This area setting unit 26 is also installed as software together with the input determination unit 24.

  The assignment of the area location on the input surface 7a set in the area setting unit 26, the size of the area, and the distribution of functions for each area are set in the setting menu mode, the input pad 7 and the right button switch. It can be changed by operating 8a and the left button switch 9a.

  In this embodiment, as shown in FIG. 2, the area setting unit 26 sets the first functional area 16 and the second functional area 17 on the input surface 7a. The first functional region 16 is a vertically long region extending with a constant width dimension in the Ya-Yb direction along the side 7b on the Xa side of the input surface 7a. The second functional region 17 is a laterally long region extending with a certain width dimension in the Xa-Xb direction along the Ya side edge 7c of the input surface 7a. By switching the control unit 20 to the setting menu mode and operating the input pad 7 or the like, the width dimension of the first functional area 16 and the width dimension of the second functional area 17 can be changed. Also, the first functional area 16 can be moved to the Xb side, and the second functional area 17 can be moved to the Yb side.

  The input determination unit 24 determines which region of the input surface 7 a of the input pad 7 is touched from the XY coordinate information included in the input signal given from the pad input signal generation unit 13. When it is determined that the finger contact position is neither the first functional area 16 nor the second functional area 17, a mouse which is an external device is used from the XY locus information included in the input signal. Thus, coordinate data equivalent to that when the input signal is generated is generated and notified to the operating system 22. At this time, the cursor displayed on the display screen of the display device 6 moves in the X1-X2 direction and the Y1-Y2 direction following the moving direction of the finger touching the input surface 7a. By this operation, it is possible to select a function key or menu displayed on the screen, and execute the selected function key or menu by tapping operation or right button 8 operation.

  When the input determination unit 24 determines that the finger is touching the first functional area 16 or the second functional area 17 of the input surface 7a of the input pad 7, the movement state of the subsequent contact position of the indicator is changed. Accordingly, the process proceeds to the display movement process.

  In the display movement process, when it is detected that the contact position of the indicator moves up and down in the first functional area 16, the input determination unit 24 sends a mouse to the operating system (OS) 22. A scroll operation signal equivalent to that when the scroll bar at the right end of the screen is operated up and down is given.

  For example, as shown in FIG. 2, when the finger contact position is moved in the Yb direction along the linear locus (b) from the position (a) on the Yb side of the first functional area 16 of the input surface 7a, the display screen is displayed. A scroll operation is performed in which the image that is the content or the character string being input by the word processor moves upward (in the Y2 direction). Further, when the finger contact position is moved in the Yb direction along the linear locus (d) from the position (c) on the Ya side of the first functional area 16, a scroll operation in which the image or character string moves downward (Y1 direction). Is executed.

  Next, when the contact position of the indicator moves to the left or right in the second function area 17, the input determination unit 24 moves the scroll bar at the lower end of the screen with the mouse to the operating system (OS) 22. An operation signal equivalent to that when the operation is performed is given.

  For example, as shown in FIG. 2, when the finger contact position is moved in the Xa direction along the linear locus (e) from the position (d) on the Xb side of the second functional region 17 of the input surface 7a, the display screen is displayed. A scroll operation is performed in which the content image or character string moves to the left (X2 direction). Further, when the finger contact position is moved in the Xb direction along the linear locus (f) from the position (c) on the Xa side of the second functional area 17, the image or character string is moved in the right direction (X1 direction). The action is executed.

  Next, after the finger touching the position (a) on the Yb side of the first functional area 16 is moved in the Ya direction along the linear locus (b), the scroll operation of the image or character string in the Y2 direction is started. The finger is moved by a predetermined distance Ly or more without departing from the first functional area 16, and the finger is continuously circulated in a clockwise curved locus (g) without moving the finger from the input surface 7a and without stopping the finger. Then, the scroll operation set by the straight locus (b) continues as it is. That is, an operation signal equivalent to that when the scroll bar at the right end of the screen is operated downward with the mouse is continuously given from the input determination unit 24 to the operating system (OS) 22.

  Whether the contact position of the finger on the input surface 7a has shifted to the curved locus (g) depends on whether the vector of the linear locus (b) is continuously in the clockwise direction at a predetermined angle or more (for example, 90 degrees or more, or 180 degrees or more). After the rotation, it is determined by monitoring whether or not the finger contact position continues to change at a predetermined curvature or more. Therefore, normally, it is preferable to rotate the finger so that the diameter of the curved locus (g) does not always change. However, as long as the contact position of the finger changes at a predetermined curvature or more, the curved locus (g ) Will continue to scroll even if the curvature of) changes midway.

  The curved locus (g) may be limited to the movement of a finger only in an area that does not belong to any of the first functional area 16 and the second functional area 17, or at any place on the input surface 7a. However, as long as the finger moves along the curved locus (g), the scroll operation may be set to continue. When the first functional area 16 is set wide, the scrolling operation is set to continue only when the finger moves along the curved locus (g) within the first functional area 16. May be.

  When the finger that has slid the surface of the input surface 7a along the curved locus (g) is stopped, the scrolling of the screen stops. Thereafter, even if the finger sliding along the curved locus (g) is resumed without releasing the finger from the input surface 7a, the scroll operation of the display content is no longer performed. Alternatively, when the finger is stopped within the predetermined time, the scrolling operation may be resumed by the subsequent movement of the curved locus (g) of the finger as long as the finger does not leave the input surface 7a.

  Note that when the finger in the middle of moving along the curved locus (g) is separated from the input surface 7a, the scrolling operation is terminated. The scrolling operation is also terminated when the change in the trajectory of the finger orbiting on the input surface 7a becomes less than a predetermined curvature.

  Similarly, the finger is moved from the position (c) on the Ya side of the first functional area 16 in the Yb direction in the linear locus (d) without moving away from the first functional area 16 and beyond the predetermined distance Ly. Is continuously moved without moving away from the input surface 7a, and the scroll operation in which the display content of the screen moves downward (Y1 direction) is continued. Also in this case, after the vector in the Yb direction of the linear trajectory (d) is continuously rotated counterclockwise by a predetermined angle or more (for example, 90 degrees or more, or 180 degrees or more), the trajectory of the contact position of the finger is further predetermined. Scroll operation is continued when it keeps changing beyond the curvature.

  Next, the finger touching the input surface 7a circulates along the curved locus (g) and the display content is scrolled in the Y2 direction. Is switched to the Y1 direction. After that, as long as the finger touching the input surface 7a continues to rotate counterclockwise, the scroll operation in the Y1 direction is continued. At this time, when the vector of the curved locus (g) changes counterclockwise by a predetermined angle (for example, 90 degrees) or more and then satisfies the same condition as that of the curved locus (h), the finger contact position Is judged to have been reversed counterclockwise.

  In addition, it is determined that the locus of the contact position is reversed counterclockwise when rotating counterclockwise without stopping the finger from the clockwise curve locus (g) or without stopping for a predetermined time or longer. However, when the finger is stopped for a predetermined time or longer, the scrolling operation is not performed even if the direction of rotation of the finger is reversed thereafter.

  Similarly, when the finger contact position shifts from the straight locus (d) to the counterclockwise curved locus (h) and the display content is scrolled in the Y1 direction, the circular locus of the finger contact position is clocked. When the direction is switched around, the scroll direction of the display content is switched to the Y2 direction.

  Next, after moving from the position (d) on the Xb side of the second functional region 17 by a straight path (d) for a predetermined distance Lx or more, and subsequently moving to a counterclockwise curved path (i), the finger is curved. While scrolling around the locus (i), the scroll operation in which the display content is moving in the X2 direction is continued. Further, after moving from the position (c) on the Xa side of the second functional area 17 by the straight line locus (f) in the Xb direction by a predetermined distance Lx or more and then moving to the clockwise curve locus (j), While the circulates around the curved locus (j), the scroll operation in which the display content moves in the X1 direction is continued.

  Further, when the direction of the finger is reversed clockwise in the middle of the curved locus (i) and the reverse rotation is continued, the scroll direction of the display content is reversed from the X2 direction to the X1 direction. Similarly, when the rotation direction of the finger is reversed counterclockwise in the middle of the curved locus (j) and the reverse rotation is continued, the scroll direction of the display content is switched from the X1 direction to the X2 direction. The conditions at this time are the same as when the curve trajectory (g) is switched clockwise and when the curve trajectory (h) is switched counterclockwise.

  Next, the determination processing operation of the input determination unit 24 will be described in detail with reference to the flowcharts shown in FIGS.

  In the flowcharts of FIGS. 4 to 10, “steps 0, 1, 2, 3,...” Are indicated by “ST0, 1, 2, 3,.

  As shown in FIG. 4, when information indicating that the finger is in contact with the input surface 7 a is given from the pad input signal generation unit 13 to the input determination unit 24 in ST <b> 0, the first functional area 16 is processed in the processing flow I. It is determined whether or not a scroll operation has been performed on the second function area 17.

  When the finger contact position on the input pad 7 is stopped at step Ia of the process flow I, the process proceeds to the process of FIG.

  In ST1 to ST3 shown in FIG. 5, the scroll operation flag and the scroll direction flag, which are the history so far, are canceled, and the accumulated movement value and the like are canceled to be in the initial state. If it is determined in ST4 that the finger contact position is the position (b) on the Yb side of the first functional area 16 or the midpoint of Ya-Yb of the first functional area 16, the process proceeds to ST5. If a flag capable of scrolling in the vertical direction is set in ST5, a scroll direction flag indicating that a vertical scroll operation in the downward direction (Ya direction) is possible is set in ST6.

  When it is determined in ST7 shown in FIG. 5 that the finger contact position is the position (d) on the Xb side of the second functional area 17 or the Xa-Xb intermediate position of the second functional area 17, ST8 Transition. If a flag that enables horizontal scrolling is set in ST8, a scroll direction flag that means that horizontal scrolling operation in the right direction (Xa direction) is possible is set in ST9.

  If it is determined in ST10 that the finger contact position is the position (c) shown in FIG. 2, since it is unclear whether vertical scrolling or horizontal scrolling will be performed thereafter, the process proceeds to ST11. Set the semi-scroll operation flag.

  In step Ib of the processing flow I shown in FIG. 4, when the finger is separated from the input surface 7a, the process proceeds to ST12 shown in FIG. 6, and the scroll operation flag is canceled.

  In step Ic of flow I, when it is detected that the finger touches the input surface 7a and moves, the flow proceeds to the flow of FIG.

  In ST13, in ST13, it is determined whether the contact position of the finger is the first functional area 16, the second functional area 17, or the other area. When the finger touch position is in the first function area 16 or the second function area 17, the process proceeds to ST14, and it is determined whether the semi-scroll operation flag is set.

  When the semi-scroll operation flag is set in ST14, the process proceeds to ST15, and first the scroll operation flag and the scroll direction flag are canceled. When it is determined in ST16 that the contact position of the finger has moved to the middle of the first functional area 16 in the Ya-Yb direction, and in ST17, when vertical scrolling is set to be effective, ST18 Then, the scroll operation flag and the scroll direction flag for enabling the vertical scroll in the Yb direction are set.

  If the semi-scrolling operation flag is not set in ST14 of FIG. 7, the process proceeds to ST19. In ST19, it is determined whether or not the scroll operation flag is already set. If the scroll operation flag is set, the process proceeds to the process shown in FIG.

  If it is determined in ST21 of FIG. 8 that the vertical scroll operation is currently being performed, the process proceeds to ST22, the scroll direction flag is once canceled, and the process proceeds to ST23. If it is determined in ST23 that the contact position of the finger is in the first functional area 16, the process proceeds to ST24, and it is determined whether or not the vertical scroll operation of the display content is valid. If it is valid, the process proceeds to ST25, and the vertical scroll operation is continued as it is. If the vertical scroll is not valid in ST24, the process proceeds to ST26, the scroll operation flag is canceled, and the vertical scroll operation is terminated.

  In ST27 of FIG. 8, when the finger contact position moves to the second functional area 17 during the vertical scroll operation, the process proceeds to ST28. In ST28, the amount of movement in the Y direction before the transition to the curved locus exceeds Ly, and the movement of the finger (movement vector, curvature of the locus, etc.) that can be determined to have shifted from the vertical scroll operation to the curved locus operation. It is detected whether the scroll state is notified to the operating system (OS) 22 or not. If the amount of movement that can be determined to have shifted to the operation of the curved locus is detected in ST28, a flag indicating the operation of the curved locus is set in ST29, and the vertical scroll operation is continued as it is in ST30. That is, when it is determined that the movement of the finger reaches the curved locus even when the finger is moved to the second functional area 17 when the first functional area 16 is operated and the vertical scroll is performed. The vertical scroll operation is continued without shifting to the horizontal scroll operation.

  In ST28, when the contact position of the finger cannot be recognized as a curved locus, the process proceeds to ST31, and it is determined whether or not horizontal scrolling is possible. At this point, since the input determination unit 24 has already determined that the scroll operation is in progress, if it is determined in ST31 that the horizontal scroll is possible, the process proceeds to ST32 and the scroll direction is changed from the vertical direction to the horizontal direction. Change to If the horizontal scroll operation is not valid in ST31, the scroll operation flag is canceled in ST33, and the scroll operation itself is terminated.

  During the vertical scrolling operation of ST21, if it is determined in ST23 that the contact position of the finger is not the first functional area 16, and if it is determined in ST27 that the contact position is not the second functional area, the process proceeds to ST34. In ST34, the finger movement (movement vector, curvature of the trajectory, etc.) that can be determined to have shifted to the operation of the curved trajectory (g) after the linear movement of Ly or more in the first functional area 16 is detected, It is confirmed whether or not the scroll state is notified to the operating system (OS) 22. If it is determined in ST34 that it has moved to a curved locus, a flag indicating that the operation is a curved locus is set in ST35. In ST36, as long as the curved locus (g) continues, a vertical scroll operation is performed. Continue as it is. In ST34, when the contact position of the finger cannot be recognized as a curved locus, the process proceeds to ST37 and the scroll operation is finished.

  When the scroll operation flag is set (ST19), and when the vertical scroll operation is not being performed in ST21 of FIG. 8, it is determined that the horizontal scroll operation is being performed, and the process proceeds to ST22a and the scroll direction flag is set once. To release. Each step of ST22a to ST37a shown in FIG. 8 corresponds to an operation in which the first functional area 16 and the second functional area 17 are reversed in each step shown in ST22 to ST37.

  In ST22a to ST37a, when the finger touch position moves from the second functional area 17 to the first functional area 16 during the horizontal scrolling operation, the movement of the finger that can be determined to have shifted to the operation of the curved locus is detected. If the scroll state is notified to the operating system (OS) 22, it is determined as a curved locus and the horizontal scroll is continued as it is. Further, as shown in FIG. 2I, the horizontal scrolling operation is continued even when it is determined that a curved locus is obtained in an area that does not belong to either the first functional area 16 or the second functional area 17.

  In ST40 of FIG. 4, when it is recognized that the scrolling operation is being performed, in processing flow II, a calculation is performed to accumulate the scroll amount according to the movement amount of the finger contact position, or the finger contact position follows a curved locus. When tracing, a process for converting the movement amount into a scroll amount is performed.

  In process flow II, in ST41, the amount of movement of the finger contact position from the start of the scroll operation is accumulated. In ST42, when it is determined that the finger contact position is not a movement along a curved locus, the process moves to ST43, and the scroll operation is continued using the integrated value of the movement amount of the finger linear movement. If it is determined in ST42 that the contact position of the finger is moving along a curved locus, the process proceeds to the process shown in FIG.

  When the cumulative value of the scroll amount converted from the curve trajectory changes in ST44 of FIG. 9, the process proceeds to ST45 to update the operation vector in the curve trajectory as the latest operation vector R0, and in ST46 the past curve trajectory. Reset the accumulated value of the operation vector.

  In ST47, the movement amount of the finger contact position obtained this time is added to the operation amount of the curved locus. In ST48, when the vertical scroll process for moving the display content in the Y direction is currently being performed, the process proceeds to ST49 and the vertical scroll process is continued. If the horizontal scroll process for moving the display content in the X direction is currently being performed in ST48, the horizontal scroll process is continued in ST50.

  In ST51, an outer product value, that is, a change in the vector of the finger movement trajectory, for example, a curvature, is acquired from the updated operation vector R0 and the currently detected operation vector accumulated value S. If it is determined in ST52 that the outer product value such as the curvature is equal to or greater than the threshold value, the vector size is acquired in ST53, and the vector size is converted into the accumulated value of the vertical scroll in ST54.

  If it is determined in ST54 and ST55 that the updated operation vector R0 and the currently detected operation vector are different from each other by a predetermined angle or more, the direction of the operation flag of the curved locus is reversed in ST56 and the process proceeds to ST57. . Even when it is not determined in ST55 that the vector is inverted, the process proceeds to ST57 and the vertical scroll transfer amount is added.

  If it is not determined in ST52 that the outer product value such as curvature is equal to or greater than the threshold value, it is determined in ST58 whether the movement amount of the finger locus is equal to or greater than the threshold value. If it is determined that the movement amount is equal to or greater than the threshold value, the process proceeds to ST59 to ST62. ST59 to ST62 are the same as the processes of ST54 to ST57.

  That is, in ST52 to ST57, the scrolling operation is continued if the finger contact position is equal to or greater than the predetermined curvature, but in ST58 to ST62, even if the curvature of the finger contact position does not exceed the threshold, If it is determined from the locus that the curve locus is traced, the scroll operation is continued.

  When the scroll operation is not being performed in ST40 of FIG. 4, the process proceeds to process flow III. In ST65, 66, and 67 of the processing flow III, when it is not possible to determine that the scroll operation is being performed, or when the finger contact position is stopped during the scroll operation, the accumulated value of the scroll operation is canceled, and then the finger is moved. Add a new cumulative movement value.

  In ST70 shown in FIG. 4, when it is uncertain whether or not the operation is a scroll operation, the process proceeds to the process flow IV. In the process flow IV, the process shown in FIG. 10 is executed.

  In ST71 of FIG. 10, it is determined whether or not the finger contact position is in the second functional area 17. If the second functional area 17 is determined in ST71, the process proceeds to ST72, in which the cumulative value of the movement amount of the finger contact position is compared in the vertical direction (Y direction) or the horizontal direction (X direction). Is done. When the horizontal direction (X direction) movement accumulated value is larger than the vertical direction (Y direction) value, the process proceeds to ST73 and it is determined whether or not the horizontal direction movement accumulated value is larger than a threshold value. If the horizontal movement cumulative value is larger than the threshold value, it is determined in ST74 that the horizontal scroll process is being performed. In ST72, if the accumulated movement value in the vertical direction is larger than the horizontal direction, and if the accumulated movement value in the vertical direction is larger than the threshold value in ST75, scrolling is canceled in ST76.

  When it is determined in ST77 that the finger contact position is in the first functional area 16, the process proceeds to ST78, where the cumulative amount of movement of the finger contact position is the vertical direction (Y direction) and the horizontal direction (X direction). And which is greater. If the accumulated value in the vertical direction (Y direction) is larger and the accumulated moving value in the vertical direction (Y direction) is larger than the threshold value in ST79, it is determined in ST80 that the vertical scroll process is being performed. If the accumulated moving value in the horizontal direction is larger than the threshold value in ST81, the scroll process is canceled in ST82.

  In the process flow IV of FIG. 4, when the scroll process is canceled in ST83, all flags and accumulated values are canceled in ST84 and ST85.

  When the vertical scroll process and the horizontal scroll process are confirmed in ST70 of FIG.

  As shown in FIG. 11, in process flow V, in ST90, the movement accumulation values in the vertical direction and the horizontal direction are canceled. If it is determined in ST91 that the finger contact position has started horizontal scrolling in the second functional area 17, the accumulated movement value of the finger contact position is larger than the threshold value (distance Lx in FIG. 2) in ST92. Check whether or not. If it is determined in ST92 that it is larger than the threshold value, it is determined in ST93 whether or not a flag indicating that the finger contact position is a curved locus is set. When the flag is set and the finger is actually moving along the curved locus in ST94, the scroll direction flag based on the curved locus is confirmed in ST95. In ST96 and ST97, the left scroll operation or the right scroll operation of the display content is continued according to the direction indicated by the scroll direction flag.

  If it is determined in ST93 that the contact position of the finger is not a curved locus, the process proceeds to ST98, where it is determined whether the cumulative value of the movement locus of the finger in the X direction is positive or negative, and in ST99 and ST100. In accordance with the positive / negative determination, the left scroll operation or the right scroll operation of the display content is continued.

  If the finger contact position has not moved along the curved locus in ST95 even though the flag indicating the curved locus is set in ST94, the process proceeds to ST101, and the accumulated curved locus of the moving locus is accumulated. When the value is obtained, the direction flag of the curve locus is updated in ST102 and ST104 according to the sign, and in ST103 and ST105, the left scroll operation or the right scroll operation of the display content is performed according to the sign of the accumulated value. Continue.

  In ST106, it is notified to the operating system (OS) 22 that it has been determined that the operation has been shifted to the curve locus operation, and in ST107, the scroll accumulated value is updated, and the next detection output is awaited.

  If it is determined in ST91a in FIG. 11 that the finger contact position has started vertical scrolling in the first functional area 16, the process proceeds to ST92a to ST107a. The processing of ST92a to ST107a identifies whether the scroll direction is upward or downward based on the curved locus of the contact position of the finger. The processing operation is the processing operation of ST92 to ST107 and whether the direction is horizontal. The only difference is the vertical direction, the others are the same.

  After the processing flow V of FIG. 4, an operation signal is given from the input determination unit 24 to the operating system (OS) 22 in ST110.
